How to Call NOS in English — Customer Service Guide
Numbers checked against official sources: July 2026.
NOS is one of Portugal’s big three telecom providers (mobile, fibre, TV) and also runs the country’s largest cinema chain — but it is the telecom support line most expats end up needing. Here is how to get through in English.
Quick answer
Customer support (from any Portuguese network)
English? No official English line. Ask "Do you speak English?" at the start — many agents can switch, but availability varies by shift.

Before you call: have this ready
- Your NIF and/or customer number (on any NOS invoice)
- The service address or phone number on the contract
- For billing questions: the invoice number and the exact charge you are disputing
What to expect on the call
- A Portuguese-language menu sorts calls by service; staying silent or saying "assistente" usually reaches a human.
- Peak hours (lunchtime, early evening) mean longer holds — mornings are quieter.
- Keep the agent’s reference number (número de registo) at the end of the call; you will need it if you have to follow up.
